OIL BURNER.

Application filed April 26, 1922. Serial No. 556,799.

To all whom it may concern.

Be it known that I, LEO F. Noon, a citizen of the United States,residing at East Greenwich, in the county of Kent and State of RhodeIsland, have invented certain new -and useful Improvements in OilBurners, of

which the following is a specification.

This invention relates to improvements in hydrocarbon burners forforcing liquid fuel, such as crude oil, through a rotary spray burnerinto the heater,'and one of the objects of this invention is to providea motor-driven no-zzle for spraying fuel, and a blower for supplyin airunder pressure to the nozzle, a ump or forcing the liquid fuel through te nozzle and means vfor highly heating the fuel before forcing itthrough the burner system for'the purpose of thinning the fuel andreducing the force required to drive the fuel tothe burner.

A further object of the invention is to provide a casing in which thepump and blower are mounted, the casing also servingV as a means fordirecting the air from the blower to the nozzle.

A still further object of the invention is the provision of a base onwhich the motor and the casing with its contents are mounted,

to provide a complete unit which may be readily moved to and fromoperative position when desired for inspection and repairs.

With these and other objects vin view, the

invention consists ofcertain novel features of construction, as will bemore fullyv described, and particularly pointed out in the appendedclaims. i

In the accompanying drawings:

Figure 1 is a side elevation in section illustrating my improvedhydrocarbon burner apparatus all mounted as -a unit upon a movable base.

Figure 2 is an enlarged viewof the burner nozzle.

Figure 3 is a detailed front'view of the spraying head.

Figure 4 is an elevation looking at the delivery end of the apparatus,and showing the ways in which the same is mounted.

Figure 5 is an enlarged sectional view of the relief or by-pass controlvalve.

Figure 6 is a sectional view 'through the casing showing the blower orfan.

It 1s found in practice to be of advantage in the construction andoperation of hydrocarbon burners of this character to provide a unitarystructure adapted to be readily adjusted towards and from the heater inorder to nicely regulate the amount of air to be drawn in -around theoutside of the neck portion, to regulate combustion and also -to be ableto remove the whole from the intense heat after shutting down and 'whenso removed the casingmay be opened up for inspection and repairs, alsoto mount the operatmg mechanism Within a protectlng caslng and to alsoprovide means whereb that casing will serve to inclose, the.

b'oWer-fan and conduct the air therefrom to the burner nozzle, and thefollowing is a A detailed description of one means by which theseresults may be accomplished:

With reference to the drawings, 10 designates the support for myimproved burner unit, in which is slidably mounted a baseplate 11 in theways 12, a binding screw 9 being provided for locking the device in'adjusted position. On the outer end of this plate, I have mounted adriving motor 13 and on the inner end of the plate I have mounted aninclosing casing 14; for the rapidly moving parts of the apparatus,which casing is preferably divided horizontally, its upper portion 15being hinged as at 16 on one side and is provided with a clamp 17 on itsopposite side by which it may be secured in closed position.

In this casing is mounted a central driving shaft 18 designed to berapidly driven by motor 13, and on the inner end of this shaft ismounted a spray nozzle 19. This nozzle is provided with a Spray head 2Onotched on its periphery as at 21 to permit the pas sage and cause thebreaking up of the fuel into a spray as forced therethrough.

The size of thesenotches may be varied in different heads to properlyact upon fuel of different characters.

This nozzle is preferably made in a tapering form being opened' slightlyat its outer end 22 to admit a small amount of air to enter 'it at thisend, the oil entering through the supply pipe 23 and the annular channel24, the whole nozzle being mounted within an air-conducting neck 25which is preferably tapering to control the amount of -air that shall bedrawn in around its outside by -a longitudinal adjustment of the wholedevice.

On the shaft 18 and withinthe casing proper, I have mounted 'a fan orblower 26 which is-preferabl Kformed of two spaced apart plates 27 an 28between which are set a plurality of lradially-disposed.-blades`29, theplate 27 beingof slightly smaller di- ,fame'ter than plate 28, and thewall 30 of the casingis preferably located close to the periphery of theIblower and on an angle thereto whereby the air as forced radially fromthe blowerimpinges against the angular face of this Wall from which itis deflected forwardly and conducted along theouter wall of the casingdown thro-ugh the nozzle inclosing neck to supply the vburner flame withthe necessary oxygen. i v

lin this protecting casing is preferably mountedall of the operatingmechanism including the heating element 31 and a pump J2 which latter isdriven at a comparatively yslow speed from the worm 33 on the shaft 18through the worm gear 34.

In feeding the burner oil isA drawn in by a pump 32 from a source notshown through the flexible tubing 35, pipe 36 and heater -3,1 and passedthrough then'pump out through pipe 37, pipe 38 and valve 39 and` shortpipe 23 into the spray nozzle, the

. amount permitted .to pass into this nozzle Aet being controlled by a.hand-operated valve 39 and the surplus fuel or that portion which ispumped but not used, is passed back through a by-pass valve 40,pipe'il'and flexible tube 42 to the main supply tank (not shown). l

'.Ilhel oil in passing through the electric heating unit 31 israised'nearly to the flash- IBy connecting-the supply pipes withflexible tubing the base-plate carrying the burner mechanism as aunitary structure is adaptedA to be readily moved forwardly and back toand from operating position which is found to be of advantage in devicesof this character as above described.

Thenagain by mounting the device on a base of vits own independently ofthe heater the same runs much more quietly than when supported on thewalls of the heater as is the casewith some devices of this character.My'improved burner is very simple and practical in construction, lisvery ecient in its operation and may be 'made in any size Maresca andladapted to be employed either in a household he'ateror in units oflargersizes.

The foregoing description is Adirected solely towards theconstruction*illustrated, but l desire it to be understood that llreserve the privilege of resorting to all the mechanical changes towhich the device isy susceptible, the inventionbeing defined and claims.

I claim: v v l. A `hydrocarb-on burnervcomprising a casing having an oilsupply nozzle, a blower, and a tubular tapered neck 'for conductingairfrom the blower tothe furnace surrounding said nozzle and projectinginto an opening in the furnace, said casing with its tapered neck beingmovable toward and .limited only by the termso-f the appended from thefurnace opening to control the adl 2.
